SBK Bonus Codes for Existing Customers
The headline-grabbing promotion at SBK is definitely the new customer offering. There are a couple of perks available to existing customers, though.
These typically come under the guise of odds boosts with current perks offering 20% bet builders, NBA and golf markets, whilst you can get up to a 100% increase across accumulator bets.
SBK New Customer Offers Reviewed
SBK has always offered a welcome offer, and since the bookie only focuses on sports, it has usually been quite good too. That remains the case today, somewhat.
⚽ Sports Bonus
Right now, you can claim £40 in free bets for depositing and staking £20, meaning you can double your betting funds when signing up. That sounds (and is) very good, although SBK used to be even more generous with a bet £10 get £50 deal.
The free bets, which are credited upon settlement of the qualifying bet (single bet, minimum odds 3.0), are divided as follows:
- £5 Bet Builder and £5 Multiple on settlement
- £5 Horse Racing Multiple after 24 hours
- £5 Football Bet Builder after 24 hours
- 2 x £5 Bet Builder after 48 hours
- 2 x £5 Multiple after 48 hours
Not only does the above give you £40 in free bets, but it also means you get a good variation of offers to explore over the course of a couple of days.
